References for DBContext, DBSet<> in Entity Framework

Question

I am trying to use ADO.Net Codefirst feature of latest Entity Framework 4.0. As part of that I have installed Entity Framework CTP 4 from Microsft and using Scott's tutorial to create the model first. Inside the tutorial DBContext and DBSet<> is specified. Could some tell what is the reference to be used in order to access this class.

I have used the following references however nothing happens for DBContext and DBSet<>

• System.Data.Entity
• System.Data.Entity.Design

You can use the Library Package Manager if you have it (it installs automatically with MVC 3.0).

From within your project in Visual Studio 2010, go to

Tools > Library Package Manager > Package Manager Console

From within your project in Visual Studio 2013, go to

Tools > NuGet Package Manager > Package Manager Console

In the console, after the PM> prompt, type

install-package entityframework

This will install the package and add the EntityFramework reference to your project.
